What is AS8887?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS8887 was assigned to TESATEL-AS by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS8887 currently announces 1 IPv4 block(s), totaling about 8.2 thousand addresses (8,192 in all), registered in Slovakia. Services from TESATEL-AS are reached through these addresses.
What it means to see AS8887 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS8887. That means the other end sits on the TESATEL-AS network (Slovakia). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
How to see every connection and network your devices reach
